TROLLEY-POLE.

SPECFI'SATION forming part of Letters Patent No. 697,828, dated April15, 1902.

Application filed J'uly Il, 1901. Serial No. 67,837. (No model.)

To @ZZ 10710771, it may concern:

Be it known that I, FRANK L. FowLER, a citizen of theUnitedStates,residing in the city and county of Philadelphia, State ofPennsyl- Vania, have invented a new and useful Improvement inTrolley-Poles, of which the following is a speciiication.

My invention relates to an improvement in trolley-poles; and it consistsof a sectional pole lo having a pin for securing the same together in alongitudinal direction, but permitting axial movement, and means forreturning the parts to their normal position.

It further consists of novel details of construction, all as will behereinafter set forth. Figure l represents a sectional View of a portionof a trolley-pole embodying my invention. Fig. 2 represents a sectionalview on line cc a3, Fig. l.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates a trolley-pole which is tubularor partly so and is divided into sections B and O, the 2 5 former beingsecured to the ear and latter is adapted to carry the trolley-wheelwhich is secured thereto in any suitable manner.

D designates a pin, which is preferably solid and is adapted to fitwithin the trolley- 3o pole A and is provided with a head E and the neckor reduced portion F, forming a recess G, in which is adapted to beseated the bolt H, which is secured to the section C of thetrolley-pole, and a bolt J rigidly secures the said pin D to the sectionI3 of the pole, it being noticed that the section O can turn on the pinsD as an axis, but is prevented from longitudinal movement with respectto the seetion K and L designate pins which are secured to the sectionsB and C, respectively, said pins having springs M and N secured thereto,which are coiled in the opposite direction from each other. v

The operation is as follows: In turning a curve a trolley-wheel isliable to leave the conductor or lfeeder-Wire owing to the rigidity ofthe parts; but in the present construction it will be noticed that whenthe wheel reaches the curve it can follow the conductor from 5e the factthat the section C of the trolley-pole can turn therewith by reason ofthe movable connection with the section B due to the pin D, andthe forceof the springs .I and L is overcome when the trolley reaches thestraight portion 5 5 of the conductor again. rPhe said springs Willassist in returning the parts to their normal position, and in thismanner the trolley is prevented from leaving the conductor, it beingseen that by this construction a very 6e durable pole is made, while theoperation of the parts permits the trolley-wheel to follow theconductor, and it being further evident that lrhe poles now being usedcan be employed, it merely being necessary to cut the same at the properplace and insert the pin D and attach the springs M and N.

If necessary, a suitable cover may be employed to cover the movingparts. It will be evident that various changes may be made 7o in theconstruction as herein shown and described, and I do not, therefore,desire to be limited in every instance to the form as herein shown anddescribed, but I desire to make such changes as will come within thescope of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a trolley-pole, formed in sections, one 8o of which is secured toa car and the other carrying the trolley-Wheel, a pin rigidly secured toone sect-ion and movably connected to the other section whereby onesection can turn with respect to the other section, and springs onopposite sides of said sections,each spring having one end secured toone section and the other end secured to the other section.

2. In a trolley-pole formed in sections, a pin 9o rigidly secured to onesection, means for movably securing said pin to the other section andserving as an axis therefor, pins secured to said sections and springscoiled in the other section, whereby said pin serves as oppositedirections connected with said seoan axis for said section and connectsthe same tions for holding the parts in normal position.

3. In a trolley-pole formed in sections, a pin together. rigidly securedto one section, a head on said FRANK L. FOVLER. 5 pin with a reducedneck connecting the same Witnesses:

and forming a recess around said pin, and a JOHN A. WIEDERSHEIM,

bolt seated in said recess and connected with C. D. MOVAY.
